what we claim and desire to secure by Letters Patent of the UnitedStates is 1. In a device for measuring a predetermined volume of liquidpassing therethrough, a housing connected with a source of supply andhaving a passageway for liquid, a rotor positioned in the saidpassageway, a baffie having a recessed face to receive the rotor andhaving a central portion extending thereabove in a liquid passageway,the relationship of the rotor and baffie being such that all liquidpassing through the conduit portion of the baffie passes through therotor, said rotor comprising a disc like member having apertures, andblade like members on the discharge side of the disc associated with theapertures therein whereby passage of liquid therethrough causes rotationthereof.

2. In a device for measuring a predetermined volume of liquid passingtherethrough, a housing having a chamber and providing a passageway forliquid, a rotor rotatably supported in the chamber, a bafile comprisinga plate secured in the chamber and having a recess in its lower face inwhich the rotor is positioned and a portion extending over the rotor andincluding a central conduit like portion extending upwardly into thechamber determining the minimum head under which the liquid may flow tothe rotor, said baffle including baflle plates within the said conduitlike portion leading to the rotor, and bafiie plates on the exterior ofthe conduit portion within the chamber, the two series of baiiie platesrespectively preventing rotation of the liquid body in the chamber andin the conduit.

3. In a device for measuring a predetermined volume of liquid passingtherethrough, a housing including a chamber providing a passageway forliquid, a bafile member supported in the chamber and having a centralconduit like portion extending vertically upwardly in the chamber, arotor including an apertured plate rotatably supported and centrallydisposed below the said conduit like portion of the baffle, said bafiiememher having a horizontal portion recessed to receive the rotor andproviding a chamber into which liquid from the conduit like portion maydischarge radially over the upper face of the rotor and means in thesaid conduit portion for preventing rotation of the liquid body inpassing to the rotor, the arrangement of the rotor and bafiie being suchthat all fluid passing through the conduit is discharged'to the rotor toeffect rotation thereof, and the height of the conduit like portion ofthe battle above the rotor determining the minimum head under whichliquid may flow through the rotor.

4. In a device for measuring a predetermined volume of liquid as itpasses therethrough, a housing including achamber providing a passagewayfor liquid, the inlet to the chamber being at one side thereof, a bafliemember supported in the chamber and having a central conduit likeportion extending vertically upwardly in the chamber and a horizontalportion recessed to provide a chamber of greater diameter than the saidconduit portion open through the lower face of the baffle andto whichthe conduit opens, a rotor including a fiat apertured plate rotatablysupported and centrally disposed in the baffle chamber below the saidconduit like portion of the baffie, the arrangement of the rotor andleaffle being such that all fluid passing through the conduitisdischarged to the rotorrto effect rotation thereof in passing throughthe plate apertures, the height of the conduit like portion of thebaffle above the rotor determining the minimum head under which liquidmay flow through the rotor, and means in-the chamber and associated withthe conduit like portion of the bafile for preventing rotation of liquidwhereby the liquid discharged to the rotor is practically free from eddycurrents.
